Type Fresh can take any TrueType font and make it your default system font with just a couple short taps. The app can also be used to backup and restore your current fonts which is especially useful if you're changing/updating your ROM often.

The first time you run Type Fresh, you're presented with a list of the fonts installed on your device. Most of the fonts aren't used that often (or at all). The two primary fonts to change are DroidSans and DroidSans-Bold. These should cover most situations.
